Doesn't quite work right.
Upper inconsistently allows milspec bolt to enter milspec barrel. After reading other reviews, all parts were flipped out to another upper made by Odin Works and they now function fine. The review with pictures explains my issue pretty much perfectly except my bolt would enter occasionally. Pros: Decent finish on the outside. Cons: Inconsistent functioning.

Poor quality
It is not milspec. The volume immediately below the location where the charging handle goes is out of spec and it came blemished with no forge markings whatsoever, contrary to the picture on this website.

Do not buy. Receiver is out of spec.
Bolt will enter barrel extension and pass headspace check outside of upper receiver. Bolt will not enter barrel when inside bolt carrier group because upper receiver forces CAM pin into particular clocking that disallows bolt to enter barrel extension. All hardware associated with assembly was reinstalled on Anderson and Bravo Company uppers and works fine on those. I bought TWO of these, same issues with two different barrel sets that worked on other uppers just fine so it wasn't a single fluke incident. Pros: A solid paperweight. Cons: Poor geometric dimensioning and tolerancing.
